An investigation into the efficacy of washing trucks following the transportation of pigs - a Salmonella perspective

Abstract

A National Salmonella Control Program is in place in the Republic of Ireland, which requires the categorisation of all pigs according to their Salmonella status. Herds in Categories 1, 2, and 3 have a serological prevalence of infection with Salmonella serotypes of \u3c10%, \u3e10-\u3c50% and \u3e50-\u3c100%, respectively. Transport of animals constitutes a stress which may induce shedding of salmonellae by carrier pigs. Although washing of trucks before leaving the abattoir is mandatory in the Republic of Ireland, little is known about the efficacy of the cleaning methods in use on trucks following the transportation of live pigs
